I claim: 1. An acoustic absorbing device comprising: a housing including a chamber formed therein, and including an outer peripheral wall and a bottom wall for forming said chamber of said housing, and including an outer opening end, a hood engaged into said chamber of said housing and including a plurality of orifices formed therein for allowing a sound to transmit through said hood and into said housing, an absorbing member engaged into said hood and attached to said hood and including a first gap formed between said hood and said absorbing member for allowing the sound to transmit through said first gap and into said housing, said absorbing member including a plurality of apertures formed therein for allowing the sound to transmit through said apertures of said absorbing member and into said housing, and a silencer engaged into said absorbing member and attached to said absorbing member and including a second gap formed between said silencer and said absorbing member for allowing the sound to transmit through said second gap and into said housing, said silencer including a plurality of holes formed therein for allowing the sound to transmit through said holes of said silencer and into said housing. 2. The acoustic absorbing device as claimed in claim 1, wherein said hood includes at least one catch extended inwardly for engaging with and for securing said absorbing member to said hood. 3. The acoustic absorbing device as claimed in claim 2, wherein said hood includes a ring member having said at least one catch extended from said ring member. 4. The acoustic absorbing device as claimed in claim 3, wherein said hood includes an outer member and an inner member, and said ring member is provided between said outer member and said inner member. 5. The acoustic absorbing device as claimed in claim 4, wherein said inner member of said hood includes an open bottom portion. 6. The acoustic absorbing device as claimed in claim 4, wherein said outer member of said hood is frustum-shaped. 7. The acoustic absorbing device as claimed in claim 4, wherein said inner member of said hood is cylindrical. 8. The acoustic absorbing device as claimed in claim 2, wherein said absorbing member includes a recess formed in an outer peripheral portion thereof for engaging with said at least one catch of said hood and for detachably securing said absorbing member to said hood. 9. The acoustic absorbing device as claimed in claim 8, wherein said absorbing member includes a ring member having said recess formed in said ring member. 10. The acoustic absorbing device as claimed in claim 9, wherein said absorbing member includes an outer segment and an inner segment, and said ring member is provided between said outer segment and said inner segment. 11. The acoustic absorbing device as claimed in claim 10, wherein said inner segment of said absorbing member includes a conical bottom member extended upwardly into said inner segment. 12. The acoustic absorbing device as claimed in claim 10, wherein said outer segment of said absorbing member is frustum-shaped. 13. The acoustic absorbing device as claimed in claim 10, wherein said inner segment of said absorbing member is cylindrical. 14. The acoustic absorbing device as claimed in claim 1, wherein said absorbing member includes an inner peripheral shoulder formed in an intermediate ring member for engaging with a lower element of said silencer and for detachably retaining said silencer to said absorbing member. 15. The acoustic absorbing device as claimed in claim 1, wherein said absorbing member includes an inner peripheral groove formed therein, and said silencer includes a peripheral protrusion extended therefrom for engaging with said inner peripheral groove of said absorbing member and for detachably retaining said silencer to said absorbing member. 16. The acoustic absorbing device as claimed in claim 1, wherein said silencer includes an outer cap having a plurality of said holes formed therein. 17. The acoustic absorbing device as claimed in claim 16, wherein said outer cap of said silencer includes a spherical shape. 18. The acoustic absorbing device as claimed in claim 16, wherein said outer cap of said silencer is extended out of said absorbing member. 19. The acoustic absorbing device as claimed in claim 1, wherein said housing includes at least one lock notch formed therein, and said hood includes at least one latch extended therefrom for engaging with said at least one lock notch of said housing and for detachably securing said hood to said housing. 20. The acoustic absorbing device as claimed in claim 1, wherein said housing includes at least one coupler extended out of said outer peripheral wall of said housing, and said at least one coupler includes a bore and a slot formed therein and communicating with each other.
